In some examples, the training examples may comprise images of concrete together with a label indicating a condition of the concrete (such as ordinary condition, segregation of the concrete, discoloration of the concrete, scaling of the concrete, crazing of the concrete, cracking of the concrete, curling of the concrete, etc.), the machine learning and/or deep learning algorithms may be trained using the training examples to generate an inference model that automatically identify the condition of concrete from images of concrete, and the quality indications may comprise the automatically identified condition of the concrete and/or information based (at least in part) on the automatically identified condition of the concrete.

In some embodiments, Step 730 may analyze the image data using heuristic rules to determine quality indications associate with concrete. In some examples, histograms based, at least in part, on the image data and/or regions of the image data may be generated. For example, such histograms may comprise histograms of pixel colors, of gray scale values, of image gradients, of image edges, of image corners, of low level image features, and so forth. Further, heuristic rules may be used to analyze the histograms and determine quality indications associate with concrete. For example, a heuristic rule may specify thresholds for different bins of the histogram, and the heuristic rule may determine the quality indications associate with concrete based, at least in part, on a comparison of the histogram bin values with the corresponding thresholds, for example by counting the number of bin values that exceed the corresponding threshold. In some examples, the above thresholds may be selected based, at least in part, on the type of concrete surface (for example as determined by Step 720), for example using one set of threshold values for walls, a second set of threshold values for ceilings, a third set of threshold values for stairs, and so forth.

In some embodiments, selecting a threshold (Step 740) may comprise using the object type of an object (for example, the object of Step 720) to select a threshold. For example, in response to a first object type, a first threshold value may be selected, and in response to a second object type, a second threshold value different from the first threshold value may be selected. For example, a lookup table (for example in a database) may be used to select a threshold according to an object type. In another example, a regression model configured to take as input properties of the object type and calculate a threshold value using the properties of the object type may be used to select a threshold according to an object type.

In some examples, the selection of the threshold by Step 740 may be based, at least in part, on quality indications associated with other objects. For example, the threshold may be selected to be a function of the quality indications associated with the other objects, such as mean, median, mode, minimum, maximum, value that cut the quality indications associated with the other objects to two groups of selected sizes, and so forth. In another example, a distribution of the quality indications associated with other objects may be estimated (for example, using a regression model, using density estimation algorithms, and so forth), and the threshold may be selected to be a function of the estimated distribution, such as mean, median, standard deviation, variance, coefficient of variation, coefficient of dispersion, a parameter of the beta-binomial distribution, a property of the distribution (such as a moment of the distribution), any function of the above, and so forth. For example, the distribution may be estimated to as a beta-binomial distribution, a Wallenius' noncentral hypergeometric distribution, and so forth.

In some examples, the selection of the threshold by Step 740 may be based, at least in part, on a construction plan associated with the construction site. For example, the construction plan may be analyzed to identify minimal quality indication requirements for one or more objects made of concrete, and the threshold may be selected accordingly. In one example, the minimal quality indication requirement may be specified in the construction plan, may be a requirement (such as a legal requirement, an ordinance requirement, a regulative requirement, an industry standard requirement, etc.) due to a specific object or configuration in the construction plan, and so forth.

In some examples, the object may be within a floor, and the selection of the threshold by Step 740 may be based, at least in part, on the floor. For example, the selection of the threshold may be based, at least in part, on the floor number, the floor height, properties of the floor, and so forth. For example, for an object positioned in a specified floor, a first threshold may be selected, while for an identical or similar object positioned in a different specified floor, a second threshold different from the first threshold may be selected. Further, the object may be within a building with a number of floors, and the selection of the threshold by Step 740 may be based, at least in part, on the number of floors, on the build height, on properties of the building, and so forth. For example, for an object positioned in a specified building, a first threshold may be selected, while for an identical or similar object positioned in a different specified building, a second threshold different from the first threshold may be selected. For example, a lookup table (for example in a database) may be used to select a threshold according to properties associated with the floor and/or the building. In another example, a regression model configured to take as input properties of the floor and/or the building and calculate a threshold value using the properties of the floor and/or the building type may be used to select a threshold according to the floor and/or the building.

In some examples, the selection of the threshold by Step 740 may be based, at least in part, on a beam span. For example, for an object associated with a first beam span, a first threshold may be selected, while for an identical or similar object associated with a second beam span, a second threshold different from the first threshold may be selected. For example, the beam span may be compared with a selected length, and the selection of the threshold may be based, at least in part, on a result of the comparison. In another example, a regression model configured to take as input beam span and calculate a threshold value using the beam span may be used to select a threshold according to the beam span.

In some examples, when the object is a wall of a stairway, the threshold may be selected by Step 740 to be a first value, and when the object is a wall not in a stairway, the threshold may be selected by Step 740 to be a value different than the first value. In some examples, when the object is part of a lift shaft, the threshold may be selected by Step 740 to be a first value, and when the object is not part of a lift shaft, the threshold may be selected by Step 740 to be a value different than the first value.

In some examples, the selection of the threshold by Step 740 may be based, at least in part, on multiple factors. For example, a baseline threshold may be selected according to an object type as described above. Further, in some examples the threshold may be increased or decreased (for example, by adding or subtracting a selected value, by multiplying by a selected factor, and so forth) according to at least one of quality indications associated with other objects in the construction site, a construction plan associated with the construction site, the floor (for example, properties of the floor as described above), the building (for example, properties of the building as described above), and so forth.

In some embodiments, Step 750 may comprise comparing the quality indication with the selected threshold. For example, a difference between a value of the quality indication and the selected threshold may be calculated. In another example, it may be determined whether the quality indication is higher than the selected threshold or not. In some examples, an action may be performed based on a result of the comparison of the quality indication with the selected threshold. For example, in response to a first result of the comparison, an action may be performed, and in response to a second result of the comparison, the performance of the action may be forgone. In another example, in response to a first result of the comparison, a first action may be performed, and in response to a second result of the comparison, a second action (different from the first action) may be performed. Some examples of such actions may include providing an indication to a user (as described below in relation to Step 760), updating an electronic record (for example as described below in relation to Step 1130), and so forth.

In some embodiments, Step 760 may comprise providing an indication to a user, for example based, at least in part, on the quality indication (from Step 730) and/or the selected threshold (from Step 740) and/or the result of the comparison of the quality indication with the selected threshold (from Step 750). For example, in response to a first result of the comparison, an indication may be provided to the user, and in response to a second result of the comparison, the providence of the indication may be forgone. In another example, in response to a first result of the comparison, a first indication may be provided to the user, and in response to a second result of the comparison, a second indication (different from the first indication) may be provided to the user. In some examples, the provided indication may comprise a presentation of at least part of the image data with an overlay presenting information based, at least in part, on the quality indication (for example, using a display screen, an augmented reality display system, a printer, and so forth). In some examples, indications may be provided to the user when a quality indication fails to meet some selected criterions, when a quality indication do meet some selected criterions, and so forth. In some examples, the nature and/or content of the indication provided to the user may depend on the quality indication and/or the region of the image corresponding to the quality indications and/or the objects corresponding to the quality indications and/or properties of the objects (such as position, size, color, object type, and so forth) corresponding to the quality indications. In some examples, the indications provided to the user may be provided as a: visual output, audio output, tactile output, any combination of the above, and so forth. In some examples, the amount of indications provided to the user, the events triggering the indications provided to the user, the content of the indications provided to the user, the nature of the indications provided to the user, etc., may be configurable. The indications provided to the user may be provided: by the apparatus detecting the events, through another apparatus (such as a mobile device associated with the user, mobile phone 111, tablet 112, and personal computer 113, etc.), and so forth.

In some embodiments, Step 720 may identify a plurality of regions depicting concrete in the image data obtained by Step 710. For each identified region, Step 730 may determine quality indications for the concrete depicted in the region. The quality indications of the different regions may be compared, and information may be presented to a user based, at least in part, on the result of the comparison, for example as described below. For example, Step 710 may obtain an image of a staircase made of concrete, Step 720 may identify a region for each stair, Step 730 may assign quality measure for the concrete of each stair, the stair corresponding to the lowest quality measure may be identified, and the identified lowest quality measure may be presented to the user, for example as an overlay next to the region of the stair in the image. In another example, Step 710 may obtain a 360 degrees image of a room made of concrete, Step 720 may identify a region for each wall, Step 730 may assign quality measure for the concrete of each wall, the wall corresponding to the lowest quality measure may be identified, and the identified lowest quality measure may be presented to the user, for example as an overlay on the region of the wall in the image. In yet another example, Step 710 may obtain video depicting concrete pillars, Step 720 may identify a frame and/or a region for each pillar, Step 730 may assign quality measure for the concrete of each pillar, a selected number of pillars corresponding to the highest quality measures may be identified, and the identified highest quality measures and/or corresponding pillars may be presented to the user.

In some embodiments, Step 720 may identify a region depicting concrete in the image data obtained by Step 710, and Step 730 may determine quality indications for the concrete depicted in the region. The quality indications may be compared with selected thresholds, and information may be presented to a user based, at least in part, on the result of the comparison, for example as described below. In some examples, the above thresholds may be selected based, at least in part, on the type of concrete surface (such as an object type, for example as determined by Step 720), for example using one thresholds for wall, a second threshold for ceilings, a third threshold for stairs, and so forth. For example, a quality indication may comprise a measure of the durability of the concrete and/or a measure of the strength of the concrete, the quality indication may be compared with a threshold corresponding to a minimal durability requirement and/or a minimal strength requirement, and an indication may be provided to the user when the measure of durability and/or the measure of strength does not meet the minimal requirement. In another example, a quality indication may comprise an estimated result of a test (such as compressive strength test, water permeability test, rapid chloride ion penetration test, water absorption test, initial surface absorption test, etc.), the quality indication may be compared with a threshold corresponding to minimal requirement (for example according to a standard or regulation), and an indication may be provided to the user when the estimated result of the test does not meet the minimal requirement.

FIG. 8 is a schematic illustration of example image 800 captured by an apparatus, such as apparatus 200. Image 800 may depict some objects made of concrete, such as surface 810, stair 820, stair 830, and wall 840. Method 700 may obtain image 800 using Step 710. As described above, Step 720 may identify regions of image 800 depicting objects made of concrete, such as concrete surface 810, concrete stair 820, concrete stair 830, and concrete wall 840. As described above, Step 730 may determine quality indications associated with concrete surface 810, concrete stair 820, concrete stair 830, and concrete wall 840. Information may be provided to a user based, at least in part, on the identified regions and/or determined quality indications. For example, image 800 may be presented to a user with an overlay specifying the identified regions and/or determined quality indications. Further, the determined quality indications may be compared with selected thresholds, and based on the results of the comparisons, some information may be omitted from the presentation, some information may be presented using first presentation settings (such as font type, font color, font size, background color, emphasis, contrast, transparency, etc.) while other information may be presented using other presentation settings, and so forth. In addition or alternatively to the presentation of image 800, a textual report specifying the identified regions and/or determined quality indications may be provided to the user.

FIG. 9 illustrates an example of a method 900 for providing information based on construction site images. In this example, method 900 may comprise: obtaining image data captured from a construction site (Step 710), obtaining electronic records associated with the construction site (Step 920), analyzing the image data to identify discrepancies between the construction site and the electronic records (Step 930), and providing information based on the identified discrepancies (Step 940). In some implementations, method 900 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, Step 940 may be excluded from method 900. In some implementations, one or more steps illustrated in FIG. 9 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. For example, Step 920 may be executed before and/or after and/or simultaneously with Step 710, Step 930 may be executed after and/or simultaneously with Step 710 and/or Step 920, Step 940 may be executed after and/or simultaneously with Step 930, and so forth.

In some embodiments, in Step 920 at least one electronic record associated with a construction site may be obtained. For example, the at least one electronic record obtained by Step 920 may comprise information related to objects associated with the construction site, such as objects database 605. In some examples, Step 920 may comprise obtaining at least one electronic construction plan associated with the construction site, for example from construction plans 610. In some examples, Step 920 may comprise obtaining at least one electronic as-built model associated with the construction site, for example from as-built models 615. In some examples, Step 920 may comprise obtaining at least one electronic project schedule associated with the construction site, for example from project schedules 620. In some examples, Step 920 may comprise obtaining at least one electronic financial record associated with the construction site, for example from financial records 625. In some examples, Step 920 may comprise obtaining at least one electronic progress record associated with the construction site, for example from progress records 630. In some examples, Step 920 may comprise obtaining information related to at least one safety issue associated with the construction site, for example from safety records 635. In some examples, Step 920 may comprise obtaining information related to at least one construction error associated with the construction site, for example from construction errors 640.

In some examples, Step 920 may comprise receiving the at least one electronic record associated with a construction site using one or more communication devices, such as communication modules 230, internal communication modules 440, external communication modules 450, and so forth. In some examples, Step 920 may comprise reading the at least one electronic record associated with a construction site from memory units, such as memory units 210, shared memory modules 410, and so forth. In some examples, Step 920 may comprise obtaining information related to at least one object associated with the construction site, for example from objects database 605, by analyzing image data depicting the object in the construction site (for example using Step 1120 as described below), by analyzing electronic records comprising information about the object as described below, and so forth. In some examples, Step 920 may comprise creating the at least one electronic record associated with a construction site, for example by using any the methods described herein. For example, electronic records comprising information related to objects in the construction site and made of concrete may be obtained by using method 700. In another example, electronic records comprising information related to discrepancies between the construction site and other electronic records may be obtained by using method 900. In yet another example, electronic records comprising information related to objects in the construction site may be obtained by using method 1100 and/or method 1300 and/or method 1600. In another example, electronic records comprising information related to financial assessments associated with the construction site may be obtained by using method 1200. In yet another example, electronic records comprising information related to entities associated with the construction site may be obtained by using method 1500.

In some embodiments, Step 930 may analyze image data captured from a construction site (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) to identify at least one discrepancy between at least one electronic record associated with the construction site (such as the at least one electronic record obtained by Step 920) and the construction site. In some examples, Step 930 may analyze the at least one electronic record and/or the image data using a machine learning model trained using training examples to identify discrepancies between the at least one electronic record and the construction site. For example, a training example may comprise an electronic record and image data with a corresponding label detailing discrepancies between the electronic record and the construction site. In some examples, Step 930 may analyze the at least one electronic record and the image data using an artificial neural network configured to identify discrepancies between the at least one electronic record and the construction site.

In some examples, when the at least one electronic record comprises a construction plan associated with the construction site (such as construction plan 610, construction plan obtained by Step 920, etc.), Step 930 may identify at least one discrepancy between the construction plan and the construction site. For example, Step 930 may analyze the construction plan and/or the image data to identify an object in the construction plan that does not exist in the construction site, to identify an object in the construction site that does not exist in the construction plan, to identify an object that has a specified location according to the construction plan and is located at a different location in the construction site (for example, to identify an object for which the discrepancy between the location according to the construction plan and the location in the construction site is above a selected threshold), to identify an object that should have a specified property according to the construction plan but has a different property in the construction site (some examples of such property may include type of the object, location of the object, shape of the object, dimensions of the object, color of the object, manufacturer of the object, type of elements in the object, setting of the object, technique of installation of the object, orientation of the object, time of object installment, etc.), to identify an object that should be associated with a specified quantity according to the construction plan but is associated with a different quantity in the construction site (some examples of such quantities may include size of the object, dimensions of the object, number of elements in the object, etc.), and so forth. For example, the image data may be analyzed to detect objects and/or to determine properties of the detected objects (for example, using Step 1120 as described below), the detected objects may be searched in the construction plan (for example using the determined properties), and Step 930 may identify objects detect in the image data that are not found in the construction plan as a discrepancies. In another example, the construction plan may be analyzed to identify objects and/or properties of the identified objects, the identified objects may be searched in the image data (for example, as described above, using the identified properties, etc.), and Step 930 may identify objects identified in the construction plan that are not found in the image data as discrepancies. In yet another example, objects found both in the image data (for example, as described above) and in the construction plan (for example, as described above) may be identified, and Step 930 may compare properties of the identified objects in the image data (for example, determined as described above) with properties of the identified objects in the construction plan to identify discrepancies. Some examples of such properties may include location of the object, quantity associated with the object (as described above), type of the object, shape of the object, dimensions of the object, color of the object, manufacturer of the object, type of elements in the object, setting of the object, technique of installation of the object, orientation of the object, time of object installment, and so forth.

In some examples, when the at least one electronic record comprises a project schedule associated with the construction site (such as project schedule 620, project schedule obtained by Step 920, etc.), Step 930 may identify at least one discrepancy between the project schedule and the construction site. For example, the image data may be associated with time (for example, the capturing time of the image data, the receiving time of the image data, the time of processing of the image data, etc.), and Step 930 may identify at least one discrepancy between a desired state of the construction site at the associated time according to the project schedule and the state of the actual construction site at the associated time as depicted in the image data. For example, the project schedule and/or the image data may be analyzed to identify an object in the construction site at a certain time that should not be in the construction site at the certain time according to the project schedule, to identify an object that should be in the construction site at a certain time according to the project schedule that is not in the construction site at the certain time, to identify an object in the construction site that is in a first state at a certain time that should be in a second state at the certain time according to the project schedule (where the first state differs from the second state, where the difference between the first state and the second state is at least a select threshold, etc.), and so forth. In some examples, the analysis of the construction plan and/or the image data to identify discrepancy between the construction plan and the construction site (for example, as described above) may use information from the project schedule to determine which discrepancies between the construction plan and the construction site are of importance at a selected time according to the project schedule, to determine which discrepancies between the construction plan and the construction site are expected (and therefore should be, for example, ignored, treated differently, etc.) at a selected time according to the project schedule, to determine which discrepancies between the construction plan and the construction site are unexpected at a selected time according to the project schedule, and so forth.

In some examples, when the at least one electronic record comprises a financial record associated with the construction site (such as financial records 625, financial records obtained by Step 920, etc.), Step 930 may identify at least one discrepancy between the financial record and the construction site. For example, the financial records and/or the image data may be analyzed to identify an object in the construction site that should not be in the construction site according to the financial record (for example, an object that was not paid for, was not ordered, that it's rental have not yet begun or have already ended, that is associated with an entity that should not be in the construction site according to the financial records, etc.), to identify an object that should be in the construction site according to the financial records that is not in the construction site (for example, an object that according to the financial records was paid for, was ordered, was delivered, was invoiced, was installed, is associated with an entity that should be in the construction site according to the financial records, etc.), to identify an object in the construction site that is in a first state at a certain time that should be in a second state at the certain time according to the financial records (for example, where the first state differs from the second state, where the difference between the first state and the second state is at least a select threshold, etc., for example, where the work for changing the state of the object to the second state was ordered, was billed, was paid for, etc.), and so forth. In some examples, the analysis of the construction plan and/or the image data to identify discrepancy between the construction plan and the construction site (for example, as described above) may use information from the financial records to determine which discrepancies between the construction plan and the construction site are of importance at a selected time according to the financial records (for example, have financial impact that is beyond a selected threshold), to determine which discrepancies between the construction plan and the construction site are not accurately reflected in the financial records, and so forth. In some examples, the analysis of the progress record and/or the image data to identify discrepancy between the progress record and the construction site (for example, as described below) may use information from the financial records to determine which discrepancies between the progress record and the construction site are of importance at a selected time according to the financial records (for example, have financial impact that is beyond a selected threshold), to determine which discrepancies between the progress record and the construction site are not accurately reflected in the financial records, and so forth.

In some examples, when the at least one electronic record comprises a progress record associated with the construction site (such as progress records 630, progress records obtained by Step 920, etc.), Step 930 may identify at least one discrepancy between the progress record and the construction site. For example, the progress records and/or the image data may be analyzed to identify an object in the construction site that should not be in the construction site according to the progress record, to identify an object that should be in the construction site according to the progress records that is not in the construction site, to identify an object in the construction site that is in a first state that should be in a second state according to the progress records (for example, where the first state differs from the second state, where the difference between the first state and the second state is at least a select threshold, etc.), to identify an action that is not reflected in the image data but that is reported as completed in the progress record, to identify an action that is reflected in the image data but is not reported as complete in the progress record, and so forth. In some examples, the analysis of the construction plan and/or the image data to identify discrepancy between the construction plan and the construction site (for example, as described above) may use information from the progress records to determine which discrepancies between the construction plan and the construction site are in contradiction to the information in the progress records, to determine which discrepancies between the construction plan and the construction site are correctly reflected at a selected time in the progress records, and so forth.

In some examples, when the at least one electronic record comprises an as-built model associated with the construction site (such as as-built model 615, as-built model obtained by Step 920, etc.), Step 930 may identify at least one discrepancy between the as-built model and the construction site. For example, Step 930 may analyze the as-built model and/or the image data to identify an object in the as-built model that does not exist in the construction site, to identify an object in the construction site that does not exist in the as-built model, to identify an object that has a specified location according to the as-built model and is located at a different location in the construction site (for example, to identify an object for which the discrepancy between the location according to the as-built model and the location in the construction site is above a selected threshold), to identify an object that should have a specified property according to the as-built model but has a different property in the construction site (some examples of such property may include type of the object, location of the object, shape of the object, dimensions of object, color of the object, manufacturer of the object, type of elements in the object, setting of the object, technique of installation of the object, orientation of the object, time of object installment, etc.), to identify an object that should be associated with a specified quantity according to the as-built model but is associated with a different quantity in the construction site (some examples of such quantities may include size of the object, length of the object, number of elements in the object, etc.), and so forth.

In some embodiments, Step 940 may provide information (for example, to a user, to another process, to an external device, etc.) based, at least in part, on the at least one discrepancy identified by Step 930. For example, in response to a first identified discrepancy, Step 940 may provide information (for example, to a user, to another process, to an external device, etc.), and in response to a second identified discrepancy, the providence of the information by Step 940 may be forgone. In another example, in response to a first identified discrepancy, Step 940 may provide first information, and in response to a second identified discrepancy, Step 940 may provide second information, different from the first information, for example, to a user, to another process, to an external device, and so forth. In some examples, Step 940 may provide information to a user as a visual output, audio output, tactile output, any combination of the above, and so forth. For example, Step 940 may provide the information to the user: by the apparatus analyzing the information (for example, an apparatus performing at least part of Step 930), through another apparatus (such as a mobile device associated with the user, mobile phone 111, tablet 112, and personal computer 113, etc.), and so forth. For example, the amount of information provided by Step 940, the events triggering the providence of information by Step 940, the content of the information provided by Step 940, and the nature of the information provided by Step 940 may be configurable.

In some examples, Step 940 may present a presentation of at least part of the image data with an overlay presenting information based, at least in part, on the at least one discrepancy identified by Step 930 (for example, using a display screen, an augmented reality display system, a printer, and so forth). For example, objects corresponding to the identified discrepancies may be marked by an overlay. In another example, information related to properties of the identified discrepancies may be presented in conjunction with the depiction of the objects corresponding to the identified discrepancies in the image data. For example, an overlay presenting desired dimensions of an object (such as a room, a wall, a doorway, a window, a tile, an electrical box, etc.) may be presented over a depiction of the object, for example as textual information specifying the desired dimensions and/or the actual dimensions, as a line or a shape demonstrating the desired dimensions, and so forth. In another example, an overlay presenting desired location of an object (such as a doorway, an electrical box, a pipe, etc.) may be presented in conjunction with a depiction of the object, for example as an arrow pointing from the depiction of the object to the correct location, as a marker marking the correct location, as textual information detailing the offset in object location, and so forth. In yet another example, an overlay presenting a desired object missing from the construction site may be presented over the image data, for example in or next to the desired location for the object, with an indication of the type and/or properties of the desired object, and so forth. In another example, an overlay marking an object in the construction site that should not be in the construction site may be presented over or next to the depiction of the object, for example including an X or a similar mark over the object, including textual information explaining the error, and so forth. In yet another example, an overlay marking an object in the construction site that has properties different from some desired properties may be presented over or next to the depiction of the object, for example including a marking of the object, including textual information detailing the discrepancies in properties, and so forth.

In some examples, Step 940 may present a visual presentation of at least part of a construction plan with markings visually presenting information based, at least in part, on the at least one discrepancy identified by Step 930 (for example, using a display screen, an augmented reality display system, a printer, and so forth). For example, objects corresponding to the identified discrepancies may be marked in the displayed construction plan. In another example, information related to properties of the identified discrepancies may be presented in conjunction with the depiction of the objects corresponding to the identified discrepancies in the construction plan. In yet another example, information may be presented as an overlay over the presentation of the construction plan, for example in similar ways to the overlay over the image data described above.

In some examples, Step 940 may present a visual presentation of at least part of a project schedule with markings visually presenting information based, at least in part, on the at least one discrepancy identified by Step 930 (for example, using a display screen, an augmented reality display system, a printer, and so forth). For example, tasks in the project schedules corresponding to the identified discrepancies may be marked in the displayed project schedule. Moreover, information about the identified discrepancies may be displayed in conjunction with the marked tasks. For example, the information about the identified discrepancies may be displayed in conjunction to the marked task and may include an amount of actual delay, an amount of predicted future delay, an amount of advance, construction errors associated with the task, and so forth.

In some examples, Step 940 may present a visual presentation of at least part of a financial record with markings visually presenting information based, at least in part, on the at least one discrepancy identified by Step 930 (for example, using a display screen, an augmented reality display system, a printer, and so forth). For example, items in the financial records (such as payments, orders, bills, deliveries, invoices, purchase orders, etc.) corresponding to the identified discrepancies may be marked in the displayed financial record. Moreover, information about the identified discrepancies may be displayed in conjunction with the marked items. For example, the information about the identified discrepancies may be displayed in conjunction to the marked item and may include an amount of budget overrun, an amount of predicted future budget overrun, a financial saving, an inconsistency in dates associated with the item, and so forth.

For example, items in the progress record corresponding to the identified discrepancies may be marked in the displayed progress record. Some examples of such items may include an action that is not reflected in the image data but that is reported as completed in the progress record, an action that is reflected in the image data but is not reported as complete in the progress record, and so forth. Moreover, information about the identified discrepancies may be displayed in conjunction with the marked items.

In some examples, Step 940 may present a visual presentation of at least part of an as-built model with markings visually presenting information based, at least in part, on the at least one discrepancy identified by Step 930 (for example, using a display screen, an augmented reality display system, a printer, and so forth). For example, objects corresponding to the identified discrepancies may be marked in the displayed as-built model. In another example, information related to properties of the identified discrepancies may be presented in conjunction with the depiction of the objects corresponding to the identified discrepancies in the as-built model. In yet another example, information may be presented as an overlay over the presentation of the as-built model, for example in similar ways to the overlay over the image data described above.

In some examples, the information provided by Step 940 may comprise safety data. For example, the at least one electronic record associated with a construction site obtained by Step 920 may comprise safety requirements associated with the construction site. Further, Step 930 may analyze image data captured from a construction site (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) to identify at least one discrepancy between the safety requirements associated with the construction site and the construction site. Further, Step 940 may provide information based, at least in part, on the at least one discrepancy between the safety requirements and the construction site identified by Step 930. For example, a type of scaffolds to be used (for example, at a specified location at the construction site) may be detailed in the safety requirements, while a different type of scaffolds (for example, less safe, incompatible, etc.) may be used in the construction site, as depicted in the image data and identified by Step 930. Further, in response to the identification of the usage of the different type of scaffolds by Step 930, Step 940 may provide information about the usage of a type of scaffolds incompatible with the safety requirements, may visually indicate the location of the incompatible scaffolds (for example, in the image data, in a construction plan, in an as-built model, etc.), and so forth.

In some examples, Step 930 may analyze image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) and/or electronic records (such as the at least one electronic record associated with a construction site obtained by Step 920) to compute a measure of the at least one discrepancy identified by Step 930. For example, Step 930 may analyze the image data and/or the electronic records using an artificial neural network configured to compute measures of the discrepancies from image data and/or electronic records. In another example, Step 930 may analyze the image data and/or the electronic records using a machine learning model trained using training examples to compute measures of the discrepancies from image data and/or electronic records. Further, the computed measure of a discrepancy may be compared with a selected threshold, and based on a result of the comparison, providing the information related to the discrepancy by Step 940 may be withheld. For example, in response to a first result of the comparison, Step 940 may provide the information, while in response to a second result of the comparison, providing the information may be delayed and/or forgone. For example, the at least one discrepancy identified by Step 930 may comprise a discrepancy in a position of an object between a construction plan and the construction site, the measure may include a length between the position according to the construction plan and the position in the construction site, and the threshold may be selected according to a legal and/or a contractual obligation associated with the construction site. In another example, the at least one discrepancy identified by Step 930 may comprise a discrepancy in a quantity associated with an object (some examples of such quantity may include size of the object, length of the object, dimensions of a room, number of elements in the object, etc.) between a construction plan and the construction site, the measure may include a difference between the quantity according to the construction plan and the quantity in the construction site, and the threshold may be selected according to a regulatory and/or a contractual obligation associated with the construction site.

Further, the image data may be analyzed to identify at least one property of the at least one object (such as position, size, color, object type, etc.), for example as described below in relation with Step 1120. In some examples, Step 940 may further provide information based on the at least one property. For example, providing the information may be further based on at least one position associated with the at least one object (such as, an actual position of the object in the construction site, a position of a depiction of the object in the image data, a planned position for the object according to a construction plan, etc.), for example by providing to the user an indicator of the position, for example, as a set of coordinates, as an indicator on a map, as an indicator on a construction plan, as an indicator in an overlay over a presentation of the image data, and so forth. In another example, providing the information may be further based on a property of the object (such as size, color, object type, quality, manufacturer, volume, weight, etc.), for example by presenting the value of the property as measured from the image data, by presenting the planned and/or required value (or range of values) for the property according to the electronic records (for example, construction plan, financial records showing the manufacturer, as-built model, etc.), by presenting the difference between the two, and so forth.

For example, an image depicting the construction error may be present to a user, for example with a visual indicator of the construction error. In another example, the location of the construction error may be indicated on a map, on a construction plan, on an as-build model, and so forth. In yet another example, textual information describing the construction error may be presented to the user. In some examples, the image data and/or the electronic records may be further analyzed to identify a type of the at least one construction error. For example, the image data may be analyzed using a machine learning model trained using training examples to determine type of construction errors from images and/or electronic records. In another example, the image data may be analyzed using an artificial neural network configured to determine a type of construction errors from images and/or electronic records. Further, based, at least in part, on the identified type of the at least one construction error, Step 940 may forgo and/or withhold providing at least part of the information. For example, in response to a first identified type of the at least one construction error, information may be provided to the user, and in response to a second identified type of the at least one construction error, Step 940 may forgo providing the information. In another example, in response to a first identified type of the at least one construction error, Step 940 may provide first information to the user, and in response to a second identified type of the at least one construction error, Step 940 may provide second information different from the first information to the user. In some examples, the image data may be further analyzed to determine a severity associated with the at least one construction error. For example, the image data and/or the electronic records may be analyzed using a machine learning model trained using training examples to determine severity of construction errors from images and/or electronic records. In another example, the image data may be analyzed using an artificial neural network configured to determine a severity of construction errors from images and/or electronic records. Further, based, at least in part, on the determined severity, Step 940 may forgo and/or withhold providing at least part of the information. For example, in response to a first determined severity, Step 940 may provide information to the user, and in response to a second determined severity, Step 940 may forgo providing the information. In another example, in response to a first determined severity, Step 940 may provide first information to the user, and in response to a second determined severity, Step 940 may provide second information different from the first information to the user.

Further, Step 930 may analyze the image data for the identification of the at least one discrepancy by comparing the first image with the second image. For example, differences between the images may be identified with relation to a first object while no differences between the images may be identified with relation to a second object, and Step 930 may identify a discrepancy when a progress record does not specify any modification of the first object and/or when a progress record specifies modification of the second object.

FIG. 11 illustrates an example of a method 1100 for updating records based on construction site images. In this example, method 1100 may comprise: obtaining image data captured from a construction site (Step 710), analyzing the image data to detect objects (Step 1120), and updating electronic records based on the detected objects (Step 1130). In some implementations, method 1100 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, Step 1130 may be excluded from method 1100. In some implementations, one or more steps illustrated in FIG. 11 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. For example, Step 1120 may be executed after and/or simultaneously with Step 710, Step 1130 may be executed after and/or simultaneously with Step 1120, and so forth.

Additionally or alternatively, Step 930 may identify a discrepancy between electronic records and the construction site as depicted in the image data, for example as described above, and in response Step 1130 may update the electronic records according to the identified discrepancy.

In some embodiments, Step 1120 may analyze image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) to detect at least one object in the construction site and/or to determine properties of objects. Some examples of such properties of objects may include type of object, position of object in the image data, position of the object in the construction site, size of the object, dimensions of the object, weight of the object, shape of the object, colors of the object, orientation of the object, state of the object, and so forth. In some examples, Step 1120 may analyze the image data using a machine learning model trained using training examples to detect objects and/or to determine properties of objects from images. For example, some training examples may include an image depicting an object together with label detailing information about the depicted object such as the type of the object, position of the object in the image, properties of the object, and so forth. Other training examples may include images that do not depict objects for detection, together with labels indicating that the images do not depict objects for detection.

In some examples, Step 1120 may analyze the image data to identify at least one position related to the at least one object detected by Step 1120, and the update to the at least one electronic record may be further based on the identified at least one position. In some examples, items and/or portions of the at least one electronic record associated with the identified at least one position may be selected, and the selected items and/or portions may be updated in the at least one electronic record, for example based on the at least one object detected by Step 1120 and/or properties of the at least one object determined by Step 1120. For example, objects in database 605 may be selected according to the identified at least one position, and the selected objects may be updated. In another example, portions of as-built model 615 and/or construction plan 610 may be selected according to the identified at least one position, and the selected portions may be updated. In some examples, a record of a position associated with the at least one object detected by Step 1120 may be updated in the at least one electronic record according to the identified at least one position, for example a position of an object may be registered in an as-built model 615, in database 605, and so forth. In some examples, the identified at least one position related to the at least one object may be compared with a position associated with the object in the at least one electronic record (for example, with a position of the object in construction plan 610), and construction errors 640 may be updated based on a result of the comparison (for example, registering a construction error in construction errors 640 when the difference in the position is above a selected threshold, and forgoing registration of a construction error when the difference is below the selected threshold).

In some examples, Step 1120 may analyze the image data to identify at least one property of the at least one object (such as position, size, color, object type, and so forth), and Step 1130 may update the at least one electronic record based, at least in part, on the at least one property. In some examples, records of the at least one electronic record associated with the identified at least one property may be selected, and Step 1130 may update the selected records in the at least one electronic record, for example based on the at least one object detected by Step 1120 and/or properties of the at least one object determined by Step 1120. For example, the selected record may be associated with a specific object type (such as tile, electrical box, etc.), and the selected records may be updated (for example to account for the tiles or the electrical boxes detected in the image data). In some examples, Step 1130 may update a record of a property associated with the at least one object detected by Step 1120 in the at least one electronic record according to the identified at least one property. In some examples, the identified at least one property related to the at least one object may be compared with a property associated with the object in the at least one electronic record (for example, with a property of the object in construction plan 610), and Step 1130 may update construction errors 640 based on a result of the comparison (for example, registering a construction error in construction errors 640 when the difference in the property is above a selected threshold, and forgoing registration of a construction error when the difference is below the selected threshold).

In some examples, the at least one electronic record associated with the construction site may comprise a searchable database, and Step 1130 may update the at least one electronic record by indexing the at least one object in the searchable database. For example, the searchable database may be searched for a record related to the at least one object, in response to a determination that the searchable database includes a record related to the at least one object, the record related to the at least one object may be updated, and in response to a determination that the searchable database do not include a record related to the at least one object, a record related to the at least one object may be added to the searchable database. In some examples, such searchable database may be indexed according to type of the objects, to properties of objects, to position of objects, to status of objects, to time the object was identified, to dimensions of the object, and so forth.

In some examples, when the image data comprises at least a first image corresponding to a first point in time and a second image corresponding to a second point in time (the elapsed time between the first point in time and the second point in time may be at least a selected duration, for example, at least an hour, at least one day, at least two days, at least one week, etc.), Step 1130 may update the at least one electronic record based, at least in part, on a comparison of the first image and the second image. For example, differences between the images may be identified with relation to a first object while no differences between the images may be identified with relation to a second object, and as a result update to the at least one electronic record may be made with relation to the first object, while updates related to the second object may be forwent. In another example, an identified difference may indicate that a new object was installed between the first point in time and the second point in time, and as result the installation of the new object may be recorded in progress records 630 (for example with a time stamp associated with the first point in time and/or the second point in time), project schedule 620 may be updated to reflect the installation of the new object (for example, before the second point in time and/or after the first point in time), as-build model 615 may be updated to reflect the installed new object, and so forth.

In some examples, the image data may comprise one or more indoor images of the construction site, the at least one object detected by Step 1120 may comprise a plurality of tiles paving an indoor floor, the at least one property determined by Step 1120 may comprise a number of tiles, and Step 1130 may update the at least one electronic record based, at least in part, on the number of tiles. For example, Step 1130 may update financial records 625 to reflect the number of tiles in the construction site, Step 1130 may update as-built model 615 with the number of tiles at selected locations in the construction site (room, balcony, selected area of a floor, selected unit, etc.), and so forth.

In some examples, the at least one electronic record may comprise at least one as-built model associated with the construction site (such as as-built model 615), and Step 1130 may update to the at least one electronic record by modifying the at least one the as-built model. For example, an as-built model may be updated to include objects detected by Step 1120 (for example by analyzing images of the construction site), to record a state and/or properties of objects in the as-built model according to the state and/or properties of the objects in the construction site as determined by Step 1120 (for example by analyzing images of the construction site), to position an object in the as-build model according to the position of the object in the construction site as determined by Step 1120 (for example by analyzing images of the construction site, according to the position of the image sensor the captured the images, etc.), and so forth.

In some examples, the at least one electronic record may comprise at least one project schedule associated with the construction site (such as project schedule 620), and Step 1130 may update the at least one electronic record by updating the at least one project schedule, for example by updating at least one projected date in the at least one project schedule. For example, Step 1120 may analyze image data captured at different points in time to determine a pace of progression, and Step 1130 may update at least one projected finish date in the at least one project schedule based on the amount of remaining work in the task and the determined pace of progression. For example, an analysis may show that a first number of units were handled within a selected elapsed time, and a pace of progression may be calculated by dividing the first number of units by the selected elapsed time. Moreover, a remaining number of units to be handled in the task may be obtained, for example from project schedule 620 and/or progress records 630. Further, the remaining number of units may be divided by the calculated pace of progression to estimate a remaining time for the task, and the projected finish date of the task may be updated accordingly. In another example, Step 1120 may analyze image data captured at a selected time to determine that a task that should have started according to project schedule 620 haven't yet started in the construction site. In response, Step 1130 may update projected dates associated with the task (such as projected starting date, projected finish date, projected intermediate dates, and so forth). In yet another example, Step 1130 may update projected date in project schedule 620 (for example as described above), and may further update other dates in project schedule 620 that depend on the updated dates. For example, a first task may start only after a second task is completed, and Step 1130 may update projected dates of the first task (such as the projected starting date, projected finish time, etc.) after the projected finish date of the second task is updated.

In some examples, the at least one electronic record may comprise at least one financial record associated with the construction site (such as financial record 625), and Step 1130 may update the at least one electronic record by updating the at least one financial record, for example by updating at least one amount in the at least one financial record. For example, Step 1120 may analyze image data captured at different points in time to determine a pace of progression, for example as described above, and Step 1130 may update at least one projected future expense (for example, updating a projected date of the projected future expense, updating a projected amount of the projected future expense, etc.) based on the determined pace of progression. In another example, Step 1120 may analyze image data to determine that a task was progressed or completed, and in response to the determination, a payment associated with the task may be approved, placed for approval, executed, etc., and the financial records may be updated by Step 1130 accordingly. In yet another example, Step 1120 may analyze image data to determine that a task was not progressed or completed as specified in an electronic record (for example not progressed or completed as planned according to project schedule 620, not progressed or completed as reported according to progress records 630, etc.), and in response to the determination a payment associated with the task may be reduced, withheld, delayed, etc., and the financial records may be updated by Step 1130 accordingly. In another example, financial assessments may be generated by analyzing image data depicting the construction site and/or electronic records associated with the construction site (for example, using Step 1230 as described below), and Step 1130 may update financial records according to the generated financial assessments, for example by recording the generated financial assessments in the financial records, by updating a financial assessment recorded in the financial records according to the generated financial assessments, in any other way described below, and so forth.

In some examples, the at least one electronic record may comprise at least one progress record associated with the construction site (such as progress record 630), and Step 1130 may update the at least one electronic record by updating the at least one progress record, for example by updating at least one progress status corresponding to at least one task in the at least one progress record. For example, Step 1120 may analyze image data to determine that a task was completed or a current percent of completion of the task, and Step 1130 may update at least one progress status corresponding to the task in the at least one progress record according to the determination. In another example, Step 1120 may analyze image data to determine that a task was not progressed or completed as specified in an electronic record (for example not progressed or completed as planned according to project schedule 620, not progressed or completed as reported according to progress records 630, etc.), and in response Step 1130 may record a delay in the at least one progress record according to the determination.

In some examples, the at least one electronic record (for example, the at least one electronic record updated by Step 1130, the at least one electronic record obtained by Step 920, etc.) may comprise information related to safety information. For example, image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) may be analyzed to identify at least one safety issue related to the at least one object detected by Step 1120, and Step 1130 may record information related to the at least one safety issue in the at least one electronic record. For example, Step 1120 may analyze the image data to identify a type of scaffolds used in the construction site, the identified type of scaffolds may be compared with safety requirements, and in response to a determination that the type of scaffolds is incompatible with the safety requirements, and Step 1130 may record a corresponding safety issue in safety records 635. In another example, Step 1120 may analyze the image data to detect a hanged object loosely connected to the ceiling, and Step 1130 may record a corresponding safety issue in safety records 635.

In some examples, the at least one electronic record (for example, the at least one electronic record updated by Step 1130, the at least one electronic record obtained by Step 920, etc.) may comprise information related to at least one construction error. For example, image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) may be analyzed to identify at least one construction error related to the at least one object detected by Step 1120, and Step 1130 may record information related to the at least one construction error in the at least one electronic record. For example, Step 1120 may analyze the image data to identify an object installed incorrectly, and in response Step 1130 may record the incorrect installation of the object as a construction error in construction errors 640. In another example, Step 930 may identify a discrepancy between electronic records (such as construction plan 610) and the construction site as depicted in the image data, for example as described above, Step 1120 may identify a construction error based on the identified discrepancy, for example as described above, and Step 1130 may record the construction error identified by Step 930 in construction errors 640.

In some examples, Step 1130 may update the at least one electronic record associated with the construction site based, at least in part, on a time associated with the image data. For example, the image data may comprise at least a first image corresponding to a first point in time and a second image corresponding to a second point in time, Step 1130 may update the at least one electronic record based, at least in part, on a comparison of the first image and the second image, as described above. In another example, Step 1120 may detect an object in the image data and/or determine properties of an object in an image data captured at a particular time (such as a particular minute, a particular hour, a particular date, etc.), and Step 1130 may record the detected object and/or the determined properties of the object together with the particular time in objects database 605. Other examples where the update is based on a time associated with the image data are described above.

In some examples, Step 1130 may update the at least one electronic record associated with the construction site based, at least in part, on a position associated with the image data. For example, Step 1120 may detect an object in the image data and/or determine properties of an object in an image data captured at a particular location (such as a particular unit, a particular room, from a particular position within the room, from a particular angle, at a particular set of coordinates specifying a location, etc.), and Step 1130 may record the detected object and/or the determined properties of the object together with the particular location in objects database 605. Other examples where the update is based on a position associated with the image data and/or on a position of objects depicted in the image data are described above.

Consistent with the present disclosure, image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) may be analyzed to detect at least one object in the construction site, for example as described above in relation with Step 1120. Further, the image data may be analyzed to identify at least one property of the at least one object (such as position, size, color, object type, and so forth), for example as described above in relation with Step 1120. The identified at least one property may be used to select at least one electronic record of a plurality of alternative electronic records associated with the construction site. Step 1130 may update the selected at least one electronic record, for example based on the detected at least one object and/or the identified at least one property. For example, the plurality of alternative electronic records may be associated with different types of objects, and the type of the object detected by Step 1120 may be used to select an electronic record associated with the type of the detected object of the plurality of alternative electronic records. In another example, the plurality of alternative electronic records may be associated with different regions of the construction site (for example, different rooms, different units, different buildings, etc.), and the position of the object detected by Step 1120 may be used to select an electronic record associated with a region corresponding to the position of the detected object of the plurality of alternative electronic records.

In some examples, the at least one electronic record (for example, the at least one electronic record updated by Step 1130, the at least one electronic record obtained by Step 920, etc.) may comprise information based on at least one image captured from at least one additional construction site. For example, the at least one electronic record may comprise information derived from image data captured from a plurality of construction sites. Moreover, the information about the plurality of construction sites may be aggregated, and statistics from the plurality of construction sites may be generated. Further, information from one construction site may be compared with information from other construction sites. In some examples, such statistics and/or comparisons may be provided to the user. In some examples, pace of progression at different construction sites may be measured from image data as described above, the measured pace of progression at the different construction sites may be aggregated in an electronic record (for example, in a database), statistics about the pace of progression may be generated and/or provided to a user, a pace of progression in one construction site may be compared to pace of progression in other construction sites, and so forth. In some examples, statistical model tying properties of the construction sites to the pace of progression may be determined (for example, using regression models, using statistical tools, using machine learning tools, etc.) based on the aggregated measured pace of progression at the different construction sites. Further, the statistical model may be used to predict a pace of progression for other construction sites from properties of the other construction sites. Additionally or alternatively, the statistical model may be used to suggest modification to a construction site in order to increase the pace of progression in that construction site. In some examples, construction errors at different construction sites may be identified from image data as described above, the identified construction errors at the different construction sites may be aggregated in an electronic record (for example, in a database), statistics about the construction errors may be generated and/or provided to a user, construction errors in one construction site may be compared to construction errors in other construction sites, and so forth. In some examples, statistical model tying properties of the construction sites to construction errors may be determined (for example, using regression models, using statistical tools, using machine learning tools, etc.) based on the aggregated construction errors from the different construction sites. Further, the statistical model may be used to predict construction errors likely to occur at other construction sites from properties of the other construction sites (for example, together with a predict amount of construction errors). Additionally or alternatively, the statistical model may be used to suggest modification to a construction site in order to avoid or decrease construction errors in that construction site.

FIG. 12 illustrates an example of a method for generating financial assessments based on construction site images. In this example, method 1200 may comprise: obtaining image data captured from a construction site (Step 710); obtaining electronic records associated with the construction site (Step 920); and generating financial assessments (Step 1230). In some implementations, method 1200 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, Step 920 may be excluded from method 1200. In some implementations, one or more steps illustrated in FIG. 12 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. For example, Step 920 may be executed before and/or after and/or simultaneously with Step 710, Step 1230 may be executed after and/or simultaneously with Step 710 and/or Step 920, and so forth.

In some embodiments, Step 1230 may analyze image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) and/or at least one electronic record (such as at least one electronic record associated with the construction site obtained by Step 920) to generate at least one financial assessment related to the construction site. In one example, the financial assessment generated by Step 1230 may be recorded in financial records 625. In another example, financial assessments in financial records 625 may be updated according to the financial assessment generated by Step 1230. In some examples, Step 1230 may analyze the image data and/or the at least one electronic record using a machine learning model trained using training examples to generate at least one financial assessment from image data and/or electronic records. In some examples, Step 1230 may analyze the image data and/or the at least one electronic record using an artificial neural network configured to generate at least one financial assessment from image data and/or electronic records.

In some examples, the image data may be analyzed to identify at least one discrepancy between the at least one electronic record and the construction site, for example by Step 930 as described above, and Step 1230 may use the identified at least one discrepancy to generate the at least one financial assessment. For example, Step 930 may analyze the image data to identify a delay with respect to a planned schedule according to a project schedule as described above, and in response to the identified delay Step 1230 may update a financial assessment of projected incomes associated with the construction site, Step 1230 may update a financial assessment of required capital associated with the construction site, and so forth. In another example, Step 930 may analyze the image data to identify a divergence from a construction plan as described above, and in response to the identified divergence Step 1230 may update a valuation of the construction project, Step 1230 may update an estimated risk associated with the construction site, and so forth. For example, a mathematical model of the projected incomes associated with the construction site and/or of the required capital associated with the construction site and/or of the valuation of a construction project and/or of estimated risks associated with the construction site may use a formula or an algorithm that takes delays and/or divergence from a construction plan as input, and Step 1230 may use the mathematical model to update the projected incomes associated with the construction site and/or the required capital associated with the construction site and/or the valuation of a construction project and/or estimated risks associated with the construction using the identified delays and/or the identified divergence from the construction plan.

In some examples, the image data may comprise at least a first image corresponding to a first point in time and a second image corresponding to a second point in time, the elapsed time between the first point in time and the second point in time may be at least a selected duration (for example, at least an hour, at least one day, at least two days, at least one week, etc.), and Step 1230 may generate at least one financial assessment based, at least in part, on a comparison of the first image and the second image. For example, the comparison may identify that a plurality of actions were performed in the construction site between the first point of time and the second point in time (some examples of such actions may include installation of objects, advancement in a process, damaging an element of the construction site, etc.), and a financial assessment associated with the first point in time may be updated according to the identified plurality of actions. In another example, the comparison may determine that fewer action than planned were performed in the construction site (for example, that no action was performed), a delay may be predicted as a response of the determination (or as described above), and the financial assessment may be updated according to the predicted delay.

In some examples, the at least one electronic record may comprise a construction plan associated with the construction site, and Step 1230 may use the construction plan to generate financial assessments. For example, an identified divergence from a construction plan may be used to generate financial assessments as described above. In another example, a mathematical model used for the financial assessment (such as a mathematical model of a risk related to a loan associated with the construction site, of a risk assessment related to an insurance policy associated with the construction site, of a valuation associated with the construction site, etc.) may use a function of properties of the construction plan (such as constructed area, bill of materials generated using the construction plan, etc.) as input factors.

In some examples, the at least one electronic record may comprise a project schedule associated with the construction site, and Step 1230 may use the project schedule to generate financial assessments. For example, an identified delay with respect to a planned schedule according to a project schedule may be used to generate financial assessments as described above. In another example, a mathematical model used for the financial assessment (such as a mathematical model of a risk related to a loan associated with the construction site, of a risk assessment related to an insurance policy associated with the construction site, of a valuation associated with the construction site, etc.) may use a function of properties of the project schedule (such as expected date of completion, amount of concurrent tasks, etc.) as input factors.

In some examples, the at least one electronic record may comprise a financial record associated with the construction site, and Step 1230 may use the financial record to generate financial assessments. For example, unplanned expenses and/or delayed expenses in the financial record may be used to generate financial assessments. In another example, a mathematical model used for the financial assessment (such as a mathematical model of a risk related to a loan associated with the construction site, of a risk assessment related to an insurance policy associated with the construction site, of a valuation associated with the construction site, etc.) may use a function of details from the financial records (such as total expenses to date, planned expenses, late payments, bill of materials, etc.) as input factors.

In some examples, the at least one electronic record may comprise a progress record associated with the construction site, and Step 1230 may use the progress record to generate financial assessments. For example, at least one progress status from the progress records may be used to generate financial assessments. In another example, a mathematical model used for the financial assessment (such as a mathematical model of a risk related to a loan associated with the construction site, of a risk assessment related to an insurance policy associated with the construction site, of a valuation associated with the construction site, etc.) may use a function of details from the progress records (such as delays, percent of completion of tasks, etc.) as input factors.

In some examples, Step 1230 may generate at least one financial assessment based, at least in part, on a position associated with at least part of the image data. For example, Step 1120 may detect an object in the image data and/or determine properties of an object in an image data captured at a particular location (such as a particular unit, a particular room, from a particular position within the room, from a particular angle, at a particular set of coordinates specifying a location, etc.) as described above, Step 1130 may update electronic records based on the detected object and/or the determined properties of the object together with the particular location as described above, and Step 1230 may use the updated electronic records to generate the at least one financial assessment as described above. In another example, a mathematical model used for the financial assessment (such as a mathematical model of a risk related to a loan associated with the construction site, of a risk assessment related to an insurance policy associated with the construction site, of a valuation associated with the construction site, etc.) may use a function of information extracted from the image data (for example, as described above) together with the particular location as input factors.

In some examples, Step 1230 may generate at least one financial assessment based, at least in part, on a time associated with at least part of the image data (for example, capturing time of the at least part of the image data was captured, a time of processing of the at least part of the image data, and so forth). For example, the image data may comprise at least a first image corresponding to a first point in time and a second image corresponding to a second point in time, and Step 1230 may generate at least one financial assessment based, at least in part, on a comparison of the first image and the second image as described above. In another example, a mathematical model used for the financial assessment (such as a mathematical model of a risk related to a loan associated with the construction site, of a risk assessment related to an insurance policy associated with the construction site, of a valuation associated with the construction site, etc.) may use a function of information extracted from the image data (for example, as described above) together with the time associated with at least part of the image data as input factors.

In some examples, Step 1230 may generate at least one financial assessment comprising a risk assessment related to a loan associated with the construction site, for example as described above. In some examples, Step 1230 may generate at least one financial assessment comprising a risk assessment related to an insurance policy associated with the construction site, for example as described above. In some examples, Step 1230 may generate at least one financial assessment comprising a valuation associated with the construction site, for example as described above. For example, the valuation may comprise a valuation after a completion of construction in the construction site associated with at least part of a constructed building built in the construction site.

In some examples, image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) and/or at least one electronic record (such as at least one electronic record associated with the construction site obtained by Step 920) may be analyzed to update at least one parameter of a loan associated with the construction site. For example, a risk assessment related to a loan associated with the construction site may be generated as described above, and the at least one parameter of the loan may be updated based, at least in part, on the generated risk assessment. In another example, a valuation associated with the construction site may be generated as described above, and the at least one parameter of the loan may be updated based, at least in part, on the generated valuation.

In some examples, image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) and/or at least one electronic record (such as at least one electronic record associated with the construction site obtained by Step 920) may be analyzed to update at least one parameter of an insurance policy associated with the construction site. For example, a risk assessment related to an insurance policy associated with the construction site may be generated as described above, and at least one parameter of the insurance policy may be updated based, at least in part, on the generated risk assessment. In another example, a valuation associated with the construction site may be generated as described above, and the at least one parameter of an insurance policy associated with the construction site may be updated based, at least in part, on the generated valuation.

In some examples, Step 1120 may analyze the image data and/or the at least one electronic record to detect at least one object in the construction site, for example as described above. Further, Step 1120 may further analyze the image data and/or the at least one electronic record to identify at least one property of the at least one object, for example as described above. Step 1230 may generate at least one financial assessment based, at least in part, on the identified at least one property. For example, the image data may comprise one or more indoor images of the construction site, the at least one object may comprise a plurality of tiles paving an indoor floor, the at least one property may comprise a number of tiles, and the generated at least one financial assessment may be based, at least in part, on the number of tiles. In another example, the image data may comprise one or more indoor images of the construction site, the at least one object may comprise a wall, the at least one property may comprise area and/or percent of the wall covered by plaster, and the generated at least one financial assessment may be based, at least in part, on the area and/or percent of the wall covered by plaster.

Consistent with the present disclosure, at least one previous financial assessment related to the construction site may be accessed. Further, the at least one previous financial assessment may be compared with the at least one financial assessment generated by Step 1230 to determine a magnitude of change. The magnitude of change may be compared with a selected threshold. In some examples, in response to a determination that the magnitude of change is above the selected threshold, a notification may be provided to a user, while in response a determination that the magnitude of change is below the selected threshold, providing the notification to the user may be forgone. In some examples, in response to a determination that the magnitude of change is above the selected threshold, a first notification may be provided to a user, while in response a determination that the magnitude of change is below the selected threshold, a second notification different from the first notification may be provided to the user.

FIG. 13 illustrates an example of a method 1300 for hybrid processing of construction site images. In this example, method 1300 may comprise: obtaining image data captured from a construction site (Step 710), and analyzing the image data to attempt to recognize object depicted in the image data (Step 1320). In some examples, when the attempt to recognize the object fails, method 1300 may present at least part of the image data to a user (Step 1330), and receive feedback related to the object from the user (Step 1340). In some implementations, method 1300 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, Step 1330 and/or Step 1340 may be excluded from method 1300. In some implementations, one or more steps illustrated in

FIG. 13 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. For example, Step 1320 may be executed after and/or simultaneously with Step 710, Step 1330 may be executed after and/or simultaneously with Step 1320, and so forth.

In some embodiments, Step 1320 may analyze image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) to attempt to recognize at least one object depicted in the image data and/or to attempt to determine properties of at least one object depicted in the image data. Some examples of such properties of objects may include type of object, position of object in the image data, position of object in the construction site, size of object, weight of object, shape of object, colors of object, orientation of object, state of object, and so forth. In some examples, Step 1320 may analyze the image data using a machine learning model trained using training examples to attempt to recognize objects and/or to attempt to determine properties of objects from images, for example as described above in relation to Step 1120. In one example, the machine learning model may provide an indication that the attempt to recognize objects and/or that the attempt to determine properties of objects failed. In another example, the machine learning model may provide a confidence level associated with recognition of an object and/or with a determination of properties of objects, the confidence level may be compared with a selected threshold, and the attempt may be considered as a failure when the confidence level is lower than a selected threshold. In some examples, Step 1120 may analyze the image data using an artificial neural network configured to attempt to recognize objects and/or to attempt to determine properties of objects from images, and to provide a failure indication in case of a failure to recognize objects and/or a failure to determine properties of objects.

In some examples, in response to a failure of Step 1320 to successfully recognize the at least one object and/or to successfully determine properties of the at least one object, Step 1330 may present at least part of the image data to a user (for example, using a display screen, an augmented reality display system, a printer, and so forth) and/or Step 1340 may receive a feedback related to the at least one object from the user (for example, through a user interface, using an input device, textually using a keyboard, through speech using a microphone and speech recognition, as a selection of one or more alternative of a plurality of alternatives presented to the user by Step 1330, and so forth). For example, the failure to successfully recognize the at least one object may comprise a recognition of the at least one object with a confidence level lower than a selected threshold. In some examples, the image data may be analyzed to select the at least part of the image data that Step 1330 presents to the user. For example, at least part of the image data that depicts at least part of the object that Step 1320 failed to recognize and/or failed to determine its properties may be selected. In another example, a construction plan associated with the construction site may be used to select at least part of the image data corresponding to an object in the construction plan that Step 1320 failed to successfully recognize or to successfully determine its properties.

In some examples, the failure of Step 1320 to successfully recognize the at least one object may comprise a successful recognition of a category of the at least one object and a failure to successfully recognize a specific type within the category. Further, in response to the failure of Step 1320 to successfully recognize the at least one object, Step 1330 may present information associated with the recognized category to a user alongside the at least part of the image data. For example, a category may include “electrical box”, while specific type within the category may include “round electrical box”, “square electrical box”, “rectangular electrical box”, “shallow electrical box”, “weatherproof electrical box”, “plastic electrical box”, “metal electrical box”, and so forth. In another example, a category may include “tile”, while specific type within the category may include “marble tile”, “ceramic tile”, “terrazzo tile”, “granite tile”, “travertine tile”, “limestone tile”, and so forth. In yet another example, a category may include “pipe”, while specific type within the category may include “PEX pipe”, “PVC pipe”, “rigid copper pipe”, “ABS pipe”, “flexible copper tubing”, “galvanized steel pipe”, “cast iron pipe”, “water supply pipe”, “drainage pipe”, “electrical pipe”, and so forth.

In some examples, the failure of Step 1320 to successfully determine properties of the at least one object may comprise a successful recognition of a type of the at least one object and a failure to successfully determine at least one other property of the at least one object. Further, in response to the failure of Step 1320 to successfully determine at least one other property of the at least one object, Step 1330 may present information associated with the recognized type to a user alongside the at least part of the image data. For example, the type may include “electrical box”, and the at least one property may include at least one of size, color, position, orientation, state, material, and so forth. In another example, the type may include “pipe”, and the at least one property may include at least one of end-point, size, length, color, position, state, material, and so forth. In yet another example, the type may include “electrical wiring”, and the at least one property may include at least one of end-point, length, color, position, state, and so forth.

In some examples, in response to the failure of Step 1320 to successfully recognize the at least one object and/or to successfully determine properties of the at least one object, Step 1330 may present to the user information associated with the construction site alongside the at least part of the image data. For example, at least a part of a construction plan (for example, at least a part of a construction plan corresponding to the presented at least part of the image data) may be presented. In another example, at least a part of a progress record (for example, at least a part of a progress record corresponding to the area of the object) may be presented.

In some examples, in response to the failure of Step 1320 to successfully recognize the at least one object and/or to successfully determine properties of the at least one object, Step 1330 may present to the user information associated with the at least one object and determined by analyzing the image data alongside the at least part of the image data. For example, a size and/or a shape of the object may be determined from the image data and presented to the user. In some examples, in response to the failure of Step 1320 to successfully recognize the at least one object and/or to successfully determine properties of the at least one object, Step 1330 may present to the user information related to a position associated with the at least one object alongside the at least part of the image data. In some examples, in response to the failure of Step 1320 to successfully recognize the at least one object and/or to successfully determine properties of the at least one object, Step 1330 may present to the user information related to a position associated with at least a portion of the image data alongside the at least part of the image data (for example, position of the camera when capturing the portion of the image data, position of at least one item depicted in the portion of the image data, and so forth). In some examples, in response to the failure of Step 1320 to successfully recognize the at least one object and/or to successfully determine properties of the at least one object, Step 1330 may present to the user information related to a time associated with at least a portion of the image data alongside the at least part of the image data (for example, time the portion of the image data was captured, time the portion of the image data was recorded, and so forth).

In some examples, the attempt of Step 1320 to recognize the at least one object and/or to determine properties of the at least one object may be based, at least in part, on a construction plan associated with the construction site. For example, a position of the at least one object in the construction site (for example, as depicted in the image data) may be used to select candidate objects from a construction plan (for example, objects in proximity to a position in the construction plan corresponding to the position of the at least one object in the construction site), and the image data may be analyzed to try and select an object of the candidate objects fitting the depiction of the object in the image data (for example, selecting the most fitting object, selecting an object with a fitting score above a selected threshold, and so forth). In another example, a machine learning model trained using training examples to attempt to recognize objects and/or to attempt to determine properties of objects from images and construction plans may be used as described above. In yet another example, an artificial neural network configured to attempt to recognize objects and/or to attempt to determine properties of objects from images and construction plans may be used as described above. Further, in response to the failure to successfully recognize the at least one object, Step 1330 may present information based on the construction plan to the user alongside the at least part of the image data. For example, Step 1330 may present a portion of the construction plan corresponding to the location of the at least one object in the image data to the user alongside the at least part of the image data. In another example, Step 1330 may present to the user information from the construction plan related to objects matching a suggested object type from the attempt to recognize the object.

In some examples, a suggested object type may be obtained from the attempt of Step 1320 to recognize the at least one object, for example as described above. One or more objects may be selected from the construction plan based on the location of the at least one object in the image data, for example by selecting objects in proximity to a position in the construction plan corresponding to the location of the at least one object in the image data. One or more types of the selected one or more objects may be obtained, for example from the construction plan. Further, the failure to successfully recognize the at least one object may be identified based, at least in part, on a mismatch between the suggested object type and the one or more types of the selected one or more objects.

In some examples, a suggested object type may be obtained from the attempt of Step 1320 to recognize the at least one object, for example as described above. One or more objects matching the suggested object type in the construction plan may be selected. One or more positions specified in the construction plan for the one or more objects matching the suggested object type in the construction plan may be obtained. Further, the failure to successfully recognize the at least one object may be identified based, at least in part, on a mismatch between at least one position of the at least one object in the image data and the one or more positions specified in the construction plan.

In some examples, the attempt of Step 1320 to recognize the at least one object may be based, at least in part, on a project schedule associated with the construction site. For example, a machine learning model trained using training examples to attempt to recognize objects and/or to attempt to determine properties of objects from images and project schedule may be used as described above. In another example, an artificial neural network configured to attempt to recognize objects and/or to attempt to determine properties of objects from images and project schedule may be used as described above. In yet another example, the failure to successfully recognize the at least one object may comprise an identification of at least one discrepancy between a recognized at least one object according to the image data and the project schedule. Further, in response to the failure to successfully recognize the at least one object, information based, at least in part, on the project schedule may be presented to the user alongside the at least part of the image data. For example, Step 1330 may present a portion of the project schedule related to tasks corresponding to a position of the at least one object. In another example, Step 1330 may present a portion of the project schedule related to tasks corresponding to a suggested object type from the attempt to recognize the object.

In some examples, the attempt of Step 1320 to recognize the at least one object may be based, at least in part, on a financial record associated with the construction site. For example, a machine learning model trained using training examples to attempt to recognize objects and/or to attempt to determine properties of objects from images and financial records may be used as described above. In another example, an artificial neural network configured to attempt to recognize objects and/or to attempt to determine properties of objects from images and financial records may be used as described above. In yet another example, the failure to successfully recognize the at least one object may comprise an identification of at least one discrepancy between a recognized at least one object and the financial record. Further, in response to the failure to successfully recognize the at least one object, information based, at least in part, on the financial record may be presented to the user alongside the at least part of the image data. For example, Step 1330 may present a portion of the financial records related to the position of the at least one object. In another example, Step 1330 may present a portion of the financial records related to tasks corresponding to a suggested object type from the attempt to recognize the object.

In some examples, the attempt of Step 1320 to recognize the at least one object may be based, at least in part, on a progress record associated with the construction site. For example, a machine learning model trained using training examples to attempt to recognize objects and/or to attempt to determine properties of objects from images and progress records may be used as described above. In another example, an artificial neural network configured to attempt to recognize objects and/or to attempt to determine properties of objects from images and progress records may be used as described above. In another example, the failure to successfully recognize the at least one object may comprise an identification of at least one discrepancy between a recognized at least one object and the progress record. Further, in response to the failure to successfully recognize the at least one object, information based, at least in part, on the progress record may be presented to the user alongside the at least part of the image data. For example, Step 1330 may present a portion of the progress records related to the position of the at least one object. In another example, Step 1330 may present a portion of the progress records related to tasks corresponding to a suggested object type from the attempt to recognize the object.

FIG. 14 is a schematic illustration of a user interface 1400 consistent with an embodiment of the present disclosure. In some examples, Step 1320 may analyze image 1050 captured by Step 710 in an attempt to recognize object 1065. Further, in response to a failure of Step 1320 to recognize object 1065, Step 1330 may present image 1405 to a user using user interface 1400. Image 1405 may comprise at least part of image 1050 depicting object 1065. Further, user interface 1400 may comprise an overlay over image 1405 emphasizing object 1065, such as emphasize box 1410. Further, user interface 1400 may comprise a presentation of query 1415 to the user requesting the user to identify object 1065. Step 1340 may receive from the user an identified object type for object 1065 through user interface 1400. In another example, user interface 1400 may comprise a presentation of query to the user requesting the user to provide a property of object 1065 (not shown), and Step 1340 may receive from the user a property of object 1065 through user interface 1400. In yet another example, Step 1340 may receive from the user through user interface 1400 an indication that the type of the object and/or the property of the object in unknown to the user.

FIG. 15 illustrates an example of a method 1500 for ranking using construction site images. In this example, method 1500 may comprise: obtaining image data captured from a construction site (Step 710); analyzing the image data to detect elements associated with an entity (Step 1520); analyzing the image data to determine properties indicative of quality and associated with the detected elements (Step 1530); and rank the entity (Step 1540). In some implementations, method 1500 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, Step 1540 may be excluded from method 1500. In some implementations, one or more steps illustrated in FIG. 15 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. For example, Step 1520 may be executed after and/or simultaneously with Step 710, Step 1530 may be executed after and/or simultaneously with Step 1520, Step 1540 may be executed after and/or simultaneously with Step 1530, and so forth.

In some embodiments, Step 1520 may analyze image data (such as image data captured from the construction site using at least one image sensor and obtained by Step 710) to detect at least one element depicted in the image data and associated with an entity. In some examples, the at least one element may include an element built and/or manufactured and/or installed and/or supplied by the entity. For example, Step 1520 may analyze objects database 605 and/or project schedule 620 and/or financial records 625 and/or progress records 630 to identify elements built and/or manufactured and/or installed and/or supplied by the entity, and analyze the image data to detect the identified elements, for example as described above. In some examples, the at least one element detected by Step 1520 may include an element built and/or manufactured and/or installed and/or supplied by a second entity and affected by a task performed by the entity. For example, image data from before and after the performance of the task may be analyzed to identify elements that their state and/or condition changed, for example as described above. In some examples, the at least one element detected by Step 1520 may be selected of a plurality of alternative elements detected in the image data, for example based on the entity. For example, an analysis of the image data may detect a number of elements (for example, a number of electrical boxes, a number of walls, etc.), an analysis of the electronic records may indicate that the entity is related to a strict subset of the detected elements (for example, analysis of objects database 605 and/or project schedule 620 and/or financial records 625 and/or progress records 630 may indicate that only a strict subset of the detected elements were built and/or manufactured and/or installed and/or supplied by the entity), and the strict subset of elements may be selected of the detected elements.

In some embodiments, Step 1530 may analyze the image data to determine at least one property indicative of quality and associated with the at least one element. For example, a machine learning model may be trained using training example to determine properties indicative of quality and associated with elements from image data, and Step 1530 may analyze the image data using the trained machine learning model to determine the at least one property indicative of quality and associated with the at least one element. In another example, an artificial neural network may be configured to determine properties indicative of quality and associated with elements from image data, and Step 1530 may analyze the image data using the artificial neural network to determine the at least one property indicative of quality and associated with the at least one element. In some examples, the image data may comprise at least a first image corresponding to a first point in time and a second image corresponding to a second point in time, the elapsed time between the first point in time and the second point in time may be at least a selected duration (for example, at least an hour, at least one day, at least two days, at least one week, etc.), and Step 1530 may determine the at least one property indicative of quality based, at least in part, on a comparison of the first image and the second image. For example, the first image and the second image may be compared to determine a property of the curing process of concrete as described above. In another example, the first image and the second image may be compared to determine a property of a pace of progression of a task, as described above. In yet another example, the first image and second image may be compared to determine a change in a state of an object, as described above, and the property may be determined based on the change of the state, for example determining a first value of the property when the state change from a first state to a second state and determining a second value of the property when the state change from a first state to a third state.

In some embodiments, Step 1540 may use the at least one property indicative of quality determined by Step 1530 to generate a ranking of the entity. In some example, Step 1540 may generate a ranking comprising one or more scores. Examples of such scores may include discrete score such as “excellent”, “good”, “average” and “poor”; a numerical score; and so forth. Some examples of such scores may include a score for work pace, a score for completion of tasks on time, a score for delays, a score for quality of work, a score for not harming unrelated elements in the construction site, a score for compatibility with other elements in the construction site, and so forth. For example, the at least one property may indicate a work pace when performing tasks related to the entity (for example, “fast”, “average” and “slow”; a number of units handled within a selected time; etc.), and the calculated score may include a weighted average of the work pace for the different tasks, a mode of the work pace for the different tasks, and so forth. In another example, the at least one property may indicate that a first portion of the tasks related to the entity were completed on time, a second portion of the tasks related to the entity were minorly delayed, and a third portion of the tasks related to the entity were delayed significantly, and a score for completion of tasks on time and/or a score for delays may be computed as a function of the ratio of the first, second and third portions of the tasks of all the tasks related to the entity, as a function of the actual delay times, as a function of the actual delay time as a ratio of the planned time for each task, as a function of the actual delay time as a ratio of the entire length of performing each task, and so forth. Some examples of such function may include a weighted average of the delays or the ratio of the delays, a cumulative score that adds positive values for tasks completed on time and negative values for delayed tasks (for example, for delays beyond a selected threshold), and so forth. In yet another example, the at least one property may indicate a quality of work related to one or more objects and/or tasks related to the entity, and the calculated score may include a weighted average of the quality of work for the different objects and/or tasks, a cumulative score that adds positive values for objects and/or tasks with good quality of work and negative values for objects and/or tasks with poor quality of work, and so forth. In another example, the at least one property may indicate that an object and/or task related to the entity harmed another element at the construction site and/or was incompatible with another element and/or task in the construction site, and a score associated with the entity for not harming unrelated elements in the construction site and/or for compatibility with other elements in the construction site may be reduced due the indication that an object and/or task related to the entity harmed another element at the construction site and/or was incompatible with another element and/or task in the construction site. In some example, Step 1540 may generate a ranking of a first entity as better in at least one respect than a second entity. For example, Step 1540 may generate a first score for the first entity and a second score for the second entity as described above, and when the first score is higher than the second score rank the first entity as better than the second entity. In another example, a machine learning model may be trained using training examples to select a more compatible entity to a task of alternative entities using at least one property indicative of quality, and Step 1540 may use the trained machine learning model to generate a ranking of a first entity as better in at least one respect than a second entity, for example by selecting the more compatible entity according to the machine learning model as the better one.

In some examples, the image data may comprise one or more indoor images of the construction site, the at least one element of Step 1520 and/or Step 1530 may comprise at least one wall built by the entity, and the at least one property may comprise a quantity of plaster applied to the at least one wall. In some cases, the plaster may be applied by a different entity and still be indicative of the quality of the wall built by the entity, for example as more plaster may indicate a need to smooth depressions and/or indentations in the wall. In some examples, Step 1530 may analyze the image data to determine the quantity of plaster applied to the at least one wall. For example, the amount of plaster applied to the at least one wall may be estimated by comparing a depth image of the wall before applying the plaster to a depth image of the wall after applying the plaster, and a volume of the plaster may be estimated according to the changes between the depth images. In another example, the amount of plaster applied to the at least one wall may be estimated by a machine learning model trained using training examples to estimate amount of plaster from a 2D image of a wall before applying the plaster and a 2D image of the wall after applying the plaster. In some examples, Step 1540 may use the determined quantity of plaster applied to the at least one wall to generate the ranking of the entity. For example, the ranking of the entity may be lower when the amount of plaster applied to the at least one wall is greater, for example by reducing the ranking according to the amount of plaster, by calculating the ranking using a score function that is monotonically decreasing in the amount of plaster, and so forth.

In some examples, the at least one element Step 1520 and/or Step 1530 may comprise a room built by the entity. Further, Step 1530 may analyze the image data to determine one or more dimensions of the room, for example using a machine learning model trained using training examples to determine dimensions of a room from image data, using an artificial neural network configured to determine dimensions of a room from image data, by measuring the dimensions in 3D images of the room, and so forth. Further, Step 1540 may use the determined one or more dimensions of the room to generate the ranking of the entity. For example, the one or more dimensions may be compared with desired dimensions of the room (for example, according to a construction plan), and the ranking of the entity may be lower when the discrepancy between the determined dimensions of the room and the desired dimensions of the room is larger, for example by reducing the ranking according to the amount of discrepancy, by calculating the ranking using a score function that is monotonically decreasing in the discrepancy, and so forth.

In some examples, Step 1530 may analyze the image data to identify signs of water leaks associated with the at least one element (such as a water leak from a pipe, a water leak from an outside wall, a water leak from a ceiling, etc.), for example using a machine learning model trained using training examples to identify signs of water leaks from image data, using an artificial neural network configured to identify signs of water leaks from image data, and so forth. Further, Step 1540 may use the identified signs of water leaks to generate the ranking of the entity. For example, the ranking of the entity may be decreased when signs of water leaks are identified.

In some examples, Step 1530 may determine the at least one property based, at least in part, on at least one discrepancy between a construction plan associated with the construction site and the construction site, for example, based on at least one discrepancy identified by Step 930 between the construction plan and the construction site as described above. For example, Step 930 may identify an object in the construction plan that does not exist in the construction site as described above, and in response Step 1530 may determine the level of completeness of a task and/or the compliance to guidelines (for example, guidelines specified in the construction plan) when performing the task. In another example, Step 930 may identify an object that has a specified location according to the construction plan and is located at a different location in the construction site as described above, and in response Step 1530 may determine the compliance to the construction plan related to the installation of the object. In yet another example, Step 930 may identify an object that should have a specified property according to the construction plan but has a different property in the construction site as described above, such as a different manufacturer, and in response Step 1530 may determine that the quality of materials used is below the specified quality specified in the construction plan.

In some examples, Step 1530 may determine the at least one property based, at least in part, on at least one discrepancy between a project schedule associated with the construction site and the construction site, for example, based on at least one discrepancy identified by Step 930 between the project schedule and the construction site as described above. For example, Step 930 may identify a discrepancy between a desired state of the construction site at a selected time according to the project schedule and the state of the actual construction site at the selected time as depicted in the image data as described above, and in response Step 1530 may determine an insufficient pace of work.

In some examples, Step 1530 may determine the at least one property based, at least in part, on at least one discrepancy between a financial record associated with the construction site and the construction site, for example, based on at least one discrepancy identified by Step 930 between the financial record and the construction site as described above. For example, Step 930 may identify an object in the construction site that has a first property while the object should have a different property according to the financial records (for example, different model, different manufacturer, different size, etc.), and in response Step 1530 may determine the supply to be inadequate.

In some examples, Step 1530 may determine the at least one property based, at least in part, on at least one discrepancy between a progress record associated with the construction site and the construction site, for example, based on at least one discrepancy identified by Step 930 between the progress record and the construction site as described above. For example, Step 930 may identify an action that is not reflected in the image data but that is reported as completed in the progress record, and in response Step 1530 may determine that supervision level is inadequate. In another example, Step 930 may identify an action that is reflected in the image data but that is not reported in the progress record, and in response Step 1530 may determine that the reporting level is inadequate.

In some examples, Step 1540 may generate the ranking using information based, at least in part, on at least one image captured from at least one additional construction site. For example, information from one construction site may be compared with information from other construction sites, and the ranking may include a ranking relative to other construction sites (for example, “above average”, “average”, “below average”, “1.6 standard deviations above mean”, and so forth). In another example, an entity may be associated with a plurality of construction sites (such as a manufacturer producing products used at a plurality of construction sites, a supplier supplying products to a plurality of construction sites, a subcontractor building and/or installing elements at a plurality of construction sites, and so forth), and the ranking of the entity may be based on elements associated with the entity from the plurality of construction sites.

Consistent with the present disclosure, the at least one element detected by Step 1520 may be further associated with a first technique (such as installation technique, building technique, drying technique, and so forth), and the ranking generated by Step 1540 may be associated with the entity and the first technique. For example, the technique associated with an element may be specified in a database. In another example, the image data may be analyzed to determine the technique associated with the element, for example using a machine learning model trained using training examples to determine the technique associated with an element. In yet another example,

Step 1520 may select elements associated with a selected technique of a plurality of alternative elements. Further, Step 1520 may analyze the image data to detect an additional group of at least one element depicted in the image data and associated with the entity and a second technique, for example as described above. Step 1530 may further analyze the image data to determine an additional group of at least one property indicative of quality and associated with the additional group of at least one element. Further, Step 1540 may use the additional group of at least one property to generate a second ranking of the entity related to the second technique, for example as described above.

Consistent with the present disclosure, the at least one element detected by Step 1520 may be associated with a first group of one or more additional elements, and the ranking generated by Step 1540 may be associated with the entity and the first group. For example, in image 1050, electrical box 1055D may be associated with electrical wire 1060C and vice versa, for example due to connected functionality. In another example, in image 1700, doorway 1755 may be associated with electrical box 1760 and vice versa, for example due to proximity between the two. Further, Step 1520 may analyze the image data to detect an additional group of at least one element depicted in the image data and associated with the entity and a second group of one or more additional elements, for example as described above. Step 1530 may further analyze the image data to determine an additional group of at least one property indicative of quality and associated with the additional group of at least one element, for example as described above. Further, Step 1540 may use the additional group of at least one property to generate a second ranking of the entity related to the second group of one or more additional elements, for example as described above. In yet another example, an element (such as a pipe, a wire, a box, a tile, etc.) may be positioned adjunct and/or within to a surface (such as a wall, a floor, etc.), and therefore may be associated with the surface. Further, a first ranking may be based on elements associated with a wall and therefore the first ranking may be associated with walls, while a second ranking may be based on elements associated with a floor and therefore the second ranking may be associated with floors.

Consistent with the present disclosure, the at least one element detected by Step 1520 may be further associated with a second entity, and the ranking generated by Step 1540 may be associated with the entity and the second entity. For example, the first entity may include a manufacturer of an element and the second entity may include a subcontractor installing the element. In another example, the first entity may include a person building a wall and the second entity may include a person plastering the wall.

FIG. 16 illustrates an example of a method 1600 for annotation of construction site images. In this example, method 1600 may comprise: obtaining image data captured from a construction site (Step 710); obtaining construction plan associated with the construction site (Step 1620); analyzing the construction plan to identify a region of the image data corresponding to an object (Step 1630); presenting the image data with an indication of the identified region (Step 1640); presenting a query related to the object (Step 1650); receiving a response to the query (Step 1660); and using the response to update electronic record associated with the construction site (Step 1670). In some implementations, method 1600 may comprise one or more additional steps, while some of the steps listed above may be modified or excluded. For example, Step 1650 and/or Step 1660 and/or Step 1670 may be excluded from method 1600. In some implementations, one or more steps illustrated in FIG. 16 may be executed in a different order and/or one or more groups of steps may be executed simultaneously and vice versa. For example, Step 1620 and/or Step 1630 may be executed before and/or after and/or simultaneously with Step 710, and so forth.

Consistent with the present disclosure, image data associated with a construction site, such as image data captured from the construction site using at least one image sensor, may be obtained, for example by using Step 710 as described above. Further, Step 1620 may obtain at least one construction plan associated with the construction site (such as construction plan 610) and including information related to an object, for example by using Step 920 as described above. In some embodiments, Step 1630 may analyze the at least one construction plan obtained by Step 1620 to identify a first region of the image data corresponding to the object. For example, the at least one construction plan may include a specified position for the object, such as a unit, a room, a surface (such as a wall, a ceiling, a floor, etc.), a region within the surface, position within the surface, a set of coordinates, and so forth. Further, Step 1630 may identify a first region of the image data corresponding to the specified position for the object in the construction plan. For example, portions of the image data may be associated with different positions, such as units, rooms, surfaces (such as a wall, a ceiling, a floor, etc.), regions within the surfaces, positions within the surfaces, range of coordinates, coordinates, and so forth, and Step 1630 may identify a first region of the image data including the specified position for the object in the construction plan and/or in proximity to that specified position. In another example, the image data captured by Step 710 may be correlated with the construction plan using an image registration algorithm, and Step 1630 may identify a first region of the image data correlated to an area including the object in the construction plan. In some examples, the information related to the object in the construction plan obtained by Step 1620 may include a planned location for the object, and Step 1630 may identify a first region of the image data that may include a region of the image data corresponding to the planned location for the object, for example as described above.

In some examples, Step 1630 may analyze the image data (for example, in addition to the at least one construction plan) to identify the first region of the image data corresponding to the object. In some examples, the construction plan may specific a general position of the object. Further, an analysis of the image data may identify one or more candidate regions within the general position, and one of the one or more candidate regions may be selected as the first region of the image data corresponding to the object. For example, the construction plan may specific the general position of the object as a particular wall, an analysis of the depiction of the particular wall in the image data may identify one of the one or more candidate regions corresponding to irregularities in the pixel data depicting the walls (for example, different colors, different texture, etc.), and at least one of the candidate regions may be selected as the first region of the image data, for example based on a height, based on size, based on shape, etc. In another example, the construction plan may specific the general position of the object as a particular room, an analysis of the depiction of the particular room may detect a floor and a wall, for example as described above, and based on the type of object (for example, “floor drainage”) the candidate region may be selected to be the region depicting the floor in the image data. In some examples, an image analysis of the image data (for example using Step 1320 as described above) may identify a region of the image data that depicts the object with some probability (for example, a probability higher than a first selected threshold and/or lower than a second selected threshold), and the identified region may be selected as the first region (for example, in response to the probability being higher than the first selected threshold and/or lower than the second selected threshold).

In some examples, Step 1630 may use information based on an analysis of second image data captured from the construction site before the capturing of the image data from the construction site (for example, at least an hour before, at least one day before, at least a week before, at least a month before), for example in addition to the at least one construction plan, to identify the first region of the image data corresponding to the object. In some examples, an image analysis of the second image data (for example using Step 1120 as described above) may identify a region of the second image data that depicts the object, and a region of the image data corresponding to that region of the second image data (for example, based on image registration results) may be selected as the first region.

Step 1640 may present at least part of the image data to a user with an indication of the first region of the image data identified by Step 1630 as corresponding to the object, for example using a display screen, an augmented reality display system, a printer, and so forth. In some examples, the indication of the first region may include an overlay over the presented image data. Such overlay may include an arrow pointing to the first region, a bounding shape (such as a bounding circle, bounding rectangular box, bounding polygon, bounding free line, etc.), markings of boundaries around the first region, marking of the center of the first region, marking of an interior point or area within the first region, and so forth. In some examples, the indication of the first region may include a mask of the first region. The mask may be presented next to the image data, over the image data, and so forth. In some examples, the indication of the first region may include a presentation of the first region of the image data using first display parameters (such as color scheme, intensity, etc.) while displaying other parts of the image data with different display parameters.

In some embodiments, Step 1650 may present a query related to the object to the user, for example together with the presentation of Step 1640, for example visually, audibly, textually, using a display screen, using an augmented reality display system, a printer, audio speakers, and so forth. In some examples, the query may be related to the object and/or the image data and/or the identified first region. For example, Step 1650 may present a query about the type of the object, possibly together with a text box allowing the user to type in the type of object and/or with a presentation of plurality of alternative object types that the user may select from. In another example, Step 1650 may present a query about a property of the object (such as state, position, orientation, shape, color, dimensions, manufacturer, type of installation, etc.), possibly together with a text box allowing the user to type in the value of the property and/or with a presentation of plurality of alternative values for the property that the user may select from. In some examples, several indications of several regions and/or several queries may be presented together.

In some embodiments, Step 1660 may receive a response to the query of Step 1660 from the user and/or inputs from the user. For example, the received response and/or inputs may be related to the object and/or the image data and/or the identified first region. For example, the received response and/or inputs may be received through a user interface, using an input device, textually using a keyboard, through speech using a microphone and speech recognition, as a selection of one or more alternatives (for example, of a plurality of alternatives presented to the user by

Step 1650), and so forth. Some examples of such received response and/or inputs are described below.

In some embodiments, Step 1670 may use the response and/or the inputs received from the user by Step 1660 to update information associated with the object in at least one electronic record associated with the construction site. For example, the response and/or the inputs received from the user may indicate that the object is not in the region identified by Step 1630, and in response Step 1670 may remove the object from objects database 605 and/or record an indication that the object is not in the region identified by Step 1630 in region identified by Step 1630, may update as-built model 615 by removing the object from an area of as-built model 615 corresponding to the region identified by Step 1630, may update project schedule 620 to reflect a delay deduced from the absent of the object as described above, may update financial records 625 based on the absent of the object as described above, update progress record 630 to reflect that a task associated with the object is not completed, may update construction error 640 to reflect a construction error related to an absent of the object and/or to an incorrect location of the object, and so forth. In another example, the response and/or the inputs received from the user may indicate that the object is in the region identified by Step 1630, and in response Step 1670 may add a record of the object to objects database 605 (for example, with an indication of the position of the object as a position in the region identified by Step 1630), may update as-built model 615 by adding the object to an area of as-built model 615 corresponding to the region identified by Step 1630, may update project schedule 620 and/or update progress record 630 to reflect a task completion deduced from the present of the object as described above, may update financial records 625 based on the present of the object as described above, may update construction error 640 to reflect a construction error related to the present of the object, and so forth. In yet another example, the response and/or the inputs received from the user may indicate that the object is at a particular state and/or has a specified property, and in response Step 1670 may record the particular state and/or the specified property of the object in objects database 605, may update as-built model 615 by modifying a representation of the object in the as-built model 615 according to the particular state and/or the specified property, may update project schedule 620 and/or update progress record 630 to reflect a task progression deduced from the particular state and/or the specified property, may update financial records 625 based on the particular state and/or the specified property, may update construction error 640 to reflect a construction error related to the particular state and/or the specified property, and so forth.

In some examples, the at least one construction plan associated with the construction site and obtained by Step 1620 may include information related to a plurality of alternative objects, and at least one electronic project schedule associated with the construction site may be analyzed to select the object of Step 1630 of the plurality of alternative objects. In some examples, the project schedule may indicate expected installation dates for the plurality of alternative objects, and object corresponding to a selected time range may be selected. For example, the selected time range may be selected based on a first capturing time of the image data and/or second capturing time of image data of a previously processed past image data, for example by selecting a time range approximately starting with the second capturing time and/or approximately ending at the first capturing date, by selecting a time range including a selected time duration before the first capturing time, by selecting a time range including a selected time duration after the first capturing time, and so forth. In another example, the selected time range may be selected based on a current time, for example by selecting a time range including a selected time duration before the current time, by selecting a time range including a selected time duration after the current time, and so forth. Further, any combination of the above time ranges may be selected. In some examples, the project schedule may include an indication of active tasks at the capturing time of the image data and/or the current time, and objects related to the active tasks may be selected of the plurality of alternative objects.

Consistent with the present disclosure, Step 1650 may present a query of whether the object is depicted in the identified first region of the image data, for example as described above. Step 1660 may receive an indication of whether the object is depicted in the identified first region of the image data from the user, for example in response to the query, for example as described above. Further, Step 1670 may use the received indication of whether the object is depicted in the identified first region of the image data to update at least one electronic record associated with the construction site. For example, Step 1670 may use the received indication of whether the object is depicted in the identified first region of the image data to update at least one electronic as-built model associated with the construction site, for example as described above.

Consistent with the present disclosure, Step 1660 may receive an indication of at least one location corresponding to the object within the identified first region of the image data from the user. Further, Step 1670 may use the received indication of at least one location corresponding to the object to update at least one electronic record associated with the construction site. For example, the received indication of at least one location corresponding to the object may be used to update at least one electronic as-built model associated with the construction site, for example by adding the object to a location of the as-built model corresponding to the indicated at least one location, by setting a location of an object that already exists in the as-built model to the indicated at least one location, and so forth.

Consistent with the present disclosure, Step 1650 may present a query of a construction stage associated with the object to a user. Step 1660 may receive an indication of the construction stage associated with the object from a user, for example in response to the query. Step 1670 may use the received indication of the construction stage associated with the object to update at least one electronic record associated with the construction site. For example, Step 1670 may use the received indication of the construction stage associated with the object to update at least one electronic progress record associated with the construction site, for example by updating a status of a task associated with the object according to the received indication of the construction stage. In another example, Step 1670 may use the received indication of the construction stage associated with the object to update at least one time indication associated with a future task in at least one electronic project schedule associated with the construction site, for example when the received indication of the construction stage represent a delay in a task with respect to a plan according to the project schedule, and the delay to that task may suggest delays to future tasks due to inner-tasks relationships.

Consistent with the present disclosure, Step 1650 may present a query of a quantity associated with the object to the user. Step 1660 may receive an indication of quantity associated with the object from the user, for example in response to the query. Step 1670 may use the received indication of quantity associated with the object to update at least one electronic record associated with the construction site. For example, Step 1670 may use the received indication of quantity associated with the object to update at least one electronic financial record associated with the construction site. For example, the object may include tiles, the quantity may include number of tiles, and the number of tiles may be used to update the financial record as described above. In another example, the object may include a wall, the quantity may include area of the wall covered with plaster and/or amount of plaster used, and the area of the wall covered with plaster and/or amount of plaster used may be used to update the financial record, for example by updating information based on a bill of materials and/or by updating a completion percent of a task.

Consistent with the present disclosure, Step 1650 may present a query of a state associated with the object to the user. Step 1660 may receive an indication of the state associated with the object from the user, for example in response to the query. In some examples, Step 1670 may use the received indication of the state associated with the object to update at least one electronic record associated with the construction site. For example, the received indication of the state associated with the object may be used to identify at least one construction error associated with the object, for example as described above, and the identified at least one construction error associated with the object may be used to update the at least one electronic record associated with the construction site, such as records of construction errors 640 in a database. In some examples, the received indication of the state associated with the object may be used to identify at least one safety issue associated with the object (for example, a “loosely connected” state may indicate a safety issue, as described above, and so forth). Further, the identified at least one safety issue associated with the object may be used to update the at least one electronic record associated with the construction site, such as records of safety records 635 in a database.

Consistent with the present disclosure, the at least one construction plan associated with the construction site and obtained by Step 1620 may further include information related to a second object. Step 1630 may further analyze the at least one construction plan to identify a second region of the image data corresponding to the second object. Step 1640 may present at least part of the image data to a user with an indication of the identified second region of the image data corresponding to the second object. For example, the presentation of the indication of the identified region of the image data corresponding to the object and the presentation of the indication of the identified second region of the image data corresponding to the second object may be at least partially concurrent (for example, the indications of the two regions may be presented on the same image, two different images each with one of the two indications of the regions may be present next to each other, and so forth). In another example, the presentation of the indication of the identified region of the image data corresponding to the object and the presentation of the indication of the identified second region of the image data corresponding to the second object may be nonconcurrent.

Consistent with the present disclosure, in response to an indication received from the user by Step 1660 that the object is depicted in the identified first region of the image data, Step 1670 may make a first update to the at least one electronic record associated with the construction site, for example as described above. Consistent with the present disclosure, Step 1630 may analyze the at least one construction plan to identify a second region of the image data corresponding to the object. For example, the identified second region may include at least part of the identified first region. In another example, the identified second region may include the identified first region entirely. In yet another example, the identified second region may include no part of the identified first region. For example, in response to an indication received from the user that the object is not depicted in the identified first region of the image data, Step 1630 may select a second region of the image data corresponding to the object, for example by extending the region of the image data originally selected by Step 1630, by selecting another region from a plurality of alternative regions originally considered by Step 1630, and so forth. In response to an indication received from the user that the object is not depicted in the identified first region of the image data, Step 1640 may present at least part of the image data to a user with an indication of the identified second region of the image data corresponding to the object, for example as described above. Further, Step 1650 may present a second query of whether the object is depicted in the identified second region of the image data to the user, for example as described above. Step 1660 may receive an indication that the object is depicted in the identified second region of the image data from the user, for example in response to the second query. In response to the indication that the object is not depicted in the identified first region of the image data and to the indication that the object is depicted in the identified second region of the image data, Step 1670 may make a second update to the at least one electronic record associated with the construction site, for example as described above, and the second update may differ from the first update. For example, any update made by Step 1670 that is made according to the first region in response to an indication received from the user by Step 1660 that the object is depicted in the identified first region of the image data (as described above), may be made according to the second region in response to an indication that the object is not depicted in the identified first region of the image data and to the indication that the object is depicted in the identified second region of the image data.

Consistent with the present disclosure, in response to an indication received from the user by Step 1660 that the object is not depicted in the identified first region of the image data, method 1600 may cause capturing of additional image data from the construction site. For example, method 1600 may create a task in project schedule 620 for the capturing of the additional image data from the construction site. In another example, method 1600 may transmit a signal configured to cause at least one image sensor to capture the additional image data from the construction site. In yet another example, the additional image data may include the region identified by Step 1630. In another example, the additional image data may include an alternative location of the object. In yet another example, the additional image data may be captured at least selected time duration after the capturing of the image data presented by Step 1650. In another example, the additional image data may be obtained and/or captured using Step 710. In yet another example, the method 1600 may be repeated with the additional image data.

FIG. 17 is a schematic illustration of an example image 1700 captured by an apparatus consistent with an embodiment of the present disclosure. For example, image 1700 may depicts objects in a construction site, such as doorway 1755, electrical box 1760, a pair of electrical boxes 1765, table 1770, and so forth. As described above, Step 1630 may analyze a construction plan and/or image 1700 to identify one or more regions of the image 1700 corresponding to any of the above objects. For example, Step 1630 may identify region 1705 as corresponding to doorway 1755, may identify region 1710 as corresponding to electrical box 1760, may identify regions 1715 and 1720 as corresponding to the pair of electrical boxes 1765, may identify region 1725 as corresponding to an object occluded by table 1770 (the occluded object is not shown), and so forth. For any of the above objects and corresponding identified regions, Step 1640 may present image 1700 and/or a part of image 1700 including the corresponding identified region, together with an indication of the identified region as described above. Further, Step 1650 may present a query related to the object and/or to the corresponding identified region, as described above. Some examples of such queries may include a query of whether the object is within the region, such as “is there a doorway in region 1705”, “is there an electrical box in region 1710”, “is there an electrical box in region 1715”, “is there an electrical box in region 1720”, “is there an electrical box in region 1725”, and so forth. Some possible responses that Step 1660 may receive in return to such queries may include an indication of whether the object is with the region (for example, entirely, partially, or not at all, such as “the object is entirely within the region”, “the object is partly within the region”, “the object is not in the region”, etc.), an indication that the object is not within the region but near the region (for example, “the object is near the region”), an indication that such determination cannot be made possibly together with an indication of the reason that such determination cannot be made (for example, “impossible to determine if the object is within the region”, “impossible to determine if the object is within the region due to poor image quality”, “impossible to determine if the object is within the region due to occlusions”, etc.), and so forth. Some other examples of queries that Step 1650 may present may include queries about the location of the object within the region, such as “what is the location of an object with a region”, “what is the location of the doorway in region 1705”, “what is the location of the electrical box in region 1710”, “what is the location of the electrical boxes in region 1720”, and so forth. In response to such queries, the user may provide an indication of the location of the object (for example, marking a pixel within the object, marking an area within the object, for example using scribbles, marking the boundaries of the object, for example by using a bounding box, by using a bounding shape, by marking corners of the boundaries, etc., drawing a mask of the object, and so forth), may indicate that the object is not in the region, and so forth. Some other examples of queries that Step 1650 may present may include queries about a quantity related to the objects in the region, such as dimensions, surface area, number of items, volume, weight, “how many electrical boxes are in region 1705”, “how many electrical boxes are in region 1720”, and so forth. In response to such queries, the user may provide an indication of quantity (such as number of items, “no electrical box”, “one electrical box”, “two electrical boxes”, etc., dimensions, estimation of distance, “about two meters”, estimation of surface area, “about one square”, estimated volume, “between 10 and 15 cc”, estimated weight, “about 140 grams”, and so forth. Some other examples of queries that Step 1650 may present may include a query about a properties (such as dimensions, shape, color, state, type, etc.) of an object in the region, such as “is there a door in doorway 1755”, “what is the construction stage of electrical box 1760”, “is the wall in region 1720 plastered”, and so forth. In some examples, after receiving an indication that electrical boxes 1765 are not in region 1715, Step 1640 may present region 1720 to the user and Step 1650 may present a query of whether electrical boxes 1765 are in region 1720.
